The Compass Navigation Satellite System (CNSS), also named BeiDou-2, is China’s second-generation satellite navigation system that will be capable of providing positioning, navigation, and timing services to users on a continuous worldwide basis.
On November 2, 2006, China announced the 2nd generation Chinese navigation system, COMPASS[1]. The system is currently under development evolving from a regional system called BeiDou-1, and in the first phase will provide high-accuracy positioning services for users in China and its neighbouring regions. As of April 2011, eight satellites for Compass have been launched. According to an official report[2], " the eighth Beidou/Compass satellite marks the completion of basic function of Beidou (Compass) Navigation Satellite System " .
The long-term goal is to develop an independent global navigation satellite system similar to the GPS and GLONASS.[3]
COMPASS Arquitecture
The main layers of COMPASS architecture are:
The space segment consists of a constellation of 35 satellites, which include 5 geostationary orbit (GEO) satellites and 30 non-GSO satellites; 27 in Medium Earth Orbit (MEO) and 3 in Inclined GSO (IGSO),that will offer complete coverage of the globe.[4] [5]
The ground segment consists of a Master Control Station, an Upload Station and several Monitor Stations.[5]
The User Segment is composed by the BeiDou/Compass user terminals, which receive Compass navigation signals, determine pseudoranges (and other observables) and solve the navigation equations in order to obtain their coordinates. There is also an international cooperation in terms of Compatibility and Interoperability between BeiDou and other GNSSs, that will lead to terminals compatible with other GNSSs.[5]
